We hypothesized that IABC augmentation reduces the extent of microvascular obstruction after acute infarction.

Four patients with a mismatch had an acute infarction in more than one coronary artery territory on CMR.

This study tests the hypothesis that restraining expansion of an acute infarction preserves LV geometry and resting function.

Stroke was defined as acute infarction or intracerebral hemorrhage on a clinical or research MRI performed within 14 days of dizziness onset.

Other baseline clinical and radiographic findings, including the presence of acute infarction and hematoma, did not differ between the 3 treatment groups.

A strategy of intensive medical therapy is comparable to coronary revascularization for suppressing ischemia in stable patients after acute infarction who have preserved LV function.

Brain MRI with diffusion-weighted imaging performed 3 days after onset revealed acute infarction involving the bilateral fornices and the right genu of the corpus callosum.

Results: Of 46 patients who underwent thrombolysis within 12 h of acute infarction with confirmed cardiogenic shock, 27 underwent IABP and 19 did not.
